FILTER.

Application filed. May 28,

T 0 all whom it may concern:

Be it known that we, DAVID A. JONES and CLARENCE R. MARTIN, citizens of the United States, residing at Bartlesville, in the county of lVashington and State of Oklahoma, have invented certain new and useful Improvements in Filters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in filters and more particularly to a system of filters.

An important object of'the invention is to provide a device of this character which may be readily cleansed and which may be very cheaply manufactured without sacrificing the strength and durability of the device.

Other objects and advantages of the invention will become apparent throughout the accompanying description.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of our invention and wherein like reference characters designate like parts throughout Figure 1 is a front elevation of a filter constructed in accordance with our invention;

Figure 2 is a section on the line 22 of Figure 1;

Figure 3 is a section on the line 33 of Figure 2; and

Figure 4 is a perspective of the upper tray removed.

Referring now more particularly to the drawings. the numeral 10 indicates a casing substantially rectangular in cross section and having the side walls thereof adjacent their upper ends beveled at one corner. as indicated at 11. The front wall of the filter which terminates at the lower end of such inclined portion is provided at this point with an out-turned lip 12 for a purpose presently to appear.

Projecting inwardly from the rear wall of the casing at a point approximately alined with the upper end of the front wall are pins 18 adapted to engage in openings formed in the rear wall 14 of a strainer 15 having a reticulated bottom through which fluid may pass. as indicated at 16. The front wall of the strainer 15 is provided with a lip 15 adapted to engage and rest Specificationof Letters Patent.

upon the lip 12 of the front wall and the forward portion of the strainer is inclined, as indicated at 15*, this inclined wall tending to force the strainer re-arwardly to en gage the pins 13 and at the same time permitting oscillation of the strainer to remove the same through the opening provided by the cutting away of the side walls and the discontinuation of the front wall of the casing. This opening is provided with a pivoted closure 17 which engages against the lip 15 of the strainer 15 and prevents vertical displacement thereof.

The top wall 18 of the casing is provided with a pair of inlets 19 and a single cap 19* for these inlets so that when one inlet is in use. the other inlet may be covered to prevent the entrance of'insects and rodents. The casing is provided interiorly adjacent the lower end thereof with brackets 20 secured thereto by any suitable means and which combine to form a support for a second tray 21 similar to the tray 15. An outlet pipe 22 extends through the bottom wall 23 of the casing and has its upper end terminating immediately below the tray 21. Formed in the side wall of the outlet pipe 22 immediately above the bottom wall 23 of the casing are minute openings 24 for a purpose presently to appear.

In the use of the filter, the space intermediate the trays 21 and 15 is filled with charcoal. Water entering the upper end of the filter passes first through the tray 15 where any foreign matter of large size is removed therefrom and then through the charcoal to he purified. Passing through the tray 21. the water collects in a sediment chamber 26 formed below the tray 21 and overflows therefrom into the outlet pipe 22 and is so discharged. the sediment collecting in the sediment chamber from which it may be removed through a removable outlet cap 26 leading from the side wall thereof. lVhen the use of the filter is discontinued, the small openings 241. permit any water included with the sediment in the chamber 27 to drain through the outlet pipe 22, permitting the sediment to dry and thereby preventing freezing of the same.

Many changes being possible in the shape, size and arrangement of the various parts hereinbefore set forth without in any manner departing from the spirit of our invention, we do not limit ourselves to the specific structure thereof except as hereinafter claimed.

What we claim is:

1. In a filter of the type described, a casing, vertically spaced trays within the casing, the uppermost of said trays being disposed in spaced relation to the top of the casing and the lowermost of said trays being arranged in spaced relation to the bottom of the casing, inlets opening through the top of the casing adjacent opposite sides thereof, and an outlet opening through the bottom of the casing and extending upwardly within the casing to a point adjacent the bottom of the lowermost tray, said outlet being provided adjacent the upper surface of the bottom of the casing with minute openings.

2. In a filter of the type described, a casing, vertically spaced trays within the casing, the uppermost of said trays being disposed in spaced relation to the top of the casing and the lowermost of said trays being arranged in spaced relation to the bottom of the casing, inlets opening through the top of the easin'g adjacent opposite sides thereof, and an outlet opening through the bottom of the easing and extending upwardly within the casing to a pointadjacent the bottom of the lowermost tray, said outlet being provided adjacent the upper surface of the bottom of the casing with minute openings, said trays having reticulated bottoms and being removably supported within the casing, and a capclosed sediment removal opening formed in the side wall of the casing intermediate the lowermost tray and the bottom thereof.

3. 'In a filter of the type described, a casing substantially rectangular in form and having the side walls thereof beveled at one corner at their upper ends, the front wall of the filter terminating at the'lower end of such inclined portion to provide an opening, the front wall of the filter being provided at its upper end with an out-turned lip, pins mounted in the rear wall of the casing at a point approximately alined with the upper end of the front wall, a strainer tray having openings in the rear wall thereof adapted to engage upon said pins, and a lip formed upon the forward edge of the strained tray and adapted to rest upon the lip of said front wall.

4. In a filter of the type described, a casing substantially rectangular in form and having the side walls thereof beveled at one corner at their upper ends, the front wall of the filter terminating at. the lower end of such inclined portion to provide an opening, the front wall of the filter being provided at its upper end with an out-turned lip, pins mounted in the rear wall of the casing at a point approximately alined with the upper end of the front wall, a strainer tray having openings in the rear wall thereof adapted to engage upon said pins, a lip formed upon the forward edge of the strainer tray and adapted to rest-upon the lip of'said front wall, and a hinged closure for said opening adapted to abut the lip on said tray to maintain the same in position.

In testimony whereof we hereunto affix our signatures.
